N. M. BUDAK LOCK PROTECTOR Feb 15, 1949.

Filed Jan. 25, 1946 INVENTOR Nicholas M Badak.

B) fid/m 'I'l iis,invention relates to lock pr tectors 383111 is particularly adaptable to locks of thatype ,whichcan be unlocked from-the inside, without the use of a key, such as by operating a knob.

v In instances where locks of this type are used, it occurs often that a glass pane or thin wood panel in the door, adjacent theloclg-is broken by a culprit who reaches in and manipulates the lock to open the door.v Various types of protectors have heretofore been designed to prevent thiseondition from happening, but they have device of my invention.

1 n objectcitrus-invention isthe provision of s mplei andnovel means ifor preventing unauthorized opening of a lock fromthe outside by reaching through a broken pane or panel in a door. ,1 Another object of the invention isto provide .aprotector which can be used in connection with nearlyali standard types of door locks having a manually operated element on the, inner side of the door.

A further object of the invention i the provision of a l-ockiprotectonwhichis not dependent upon interaction with the lock in any way.

A still further object of .theinvention. is to provide a lock protector which in no way interferes with authbrizdoperation of the lock.

And still another objectresides in the provi- ,sion"of"a novel lock rotec o constructeq and arranged and'removabiymounted on the nside "of the door, in cooperation with the door jamb, when the door is closed, to cover and prevent unauthorized operation of the manually operable member of the lock.

An additional object of the invention is the provision of a lock protector which in operative position is retained in place by the door jamb.

Another object of the invention is to provide a lock protectorwhich can be readily removed when not in use.

With these and other objects in view, my invention consists in the construction, arrangement, and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, wherein:

I Field is a perspective view of the protector of Fig. 3 shown in operative position over- -the 100k. a; Referring now in detail to the drawings, ,the .glevice is shown applied to a doorili, the form shown in Figs. land 2 comprising ,a shield,, l 2 of suitable gauge sheet metal shaped by astamp- .ing operation to form a flattop surface I3, and side surfaces l4, one extending from eagh side of the top surface l3 at an angle therefrom.

aPi'ovided at the quter edges of the side surfaces 1 T4 are slid-e elements l5 formeclby foldingthe sheet metal over to form lugs l6 substantially coextensive with the .sidesurfaces i4. Y 7

, A swingable closure member I! is hingedat i9 to -the topsur face l3 at one endthereof, gand is adapted to swing into position closing o,fl"-;its dp 1. 'Shifl 2..

The opposite end Zmofthe shield I2 is referably o enfqr simplicityzjof-manufacture, but,'of course, it maybe .closed-iifj de- ,in e .latt r e ent. said c osedserrd is 3 provided, wi an op nin ofgsuffici nt size" .to permit free, unobstructed operation "ofthelock bolt.- 1 '1 Two channelgshapedlguidev strips 21 withztheir longitudinal edges;turned;.in to .formguide'ways 55.; 2.3 ar se ured "at-.DDP'OSite lends toithe doo'rgsias by wood screws 22, oneguide .strip=.2 I being 1positioned on each side of the lock, in parallel relation to each other, and extending from the free edge 24 of the door inwardly to a point be- 40 yond the inner edge of the lock designated at 25. Between the inner ends of the guide strips 2|, and inwardly beyond the lock, is a detent angle strip 26 also secured to the door by wood screws 22, or by any other preferred means.

To put the lock protector to use, the door is left ajar as shown in Fig. 1, and the slide elements l5 are inserted in the outer ends of the guide strips 2| at the free edge of the door. The closure member I1 is swung outwardly from the inner end of the shield, and the shield is then slid over the lock. After the inner end of the shield has passed over the lock, the closure member I1 is swung over the end of the shield, and continued Sliding of the shield brings the free edge of the closure member I! to bear against the detent strip 26. The detent strip 26 is positioned at such a point that when the shield I2 is in position covering the lock as just described, the outer end 20 of the shield registers approximately flush with the edge 24 of the door. When the door is then closed, the shield is held in' place by the door jamb 2? from one direction and by the detent strip 25 from the other direction.

The shield 12 may also be put into position from the other direction, 1. e., by sliding it from right to left as shown in Fig. 1, since the end 28] of the shield is preferably, as above indicated, completely open. For this procedure the door must be ajar as with the procedure first described.

In the form shown in Figs. 3 and 4, the shield i2 is shaped to fit the particular shapes of locks, whereas in the form shown in Figs. 1 and 2 the shield I2 is of general shape to fit locks of nearly all shapes. Many locks are of standard design and exist in sufficient numbers to justify standardizing the shield in a shape to conform more nearly to the shape of the lock. In the present embodiment the side surfaces M have a peculiar shape, having sharp angular depressions 29 to fit under the knob of the lock, the knob then being positioned in the enlarged portion 30 of the shield. Since the enlarged portion 38 is designed to fit closely over the knob of the lock, it is intended as an alternativeconstruction to omit the closure member I! in the form. It is impossible to reach in and operate the lock with the fingers or a tool. In such alternative construction the detent strip 26 is lengthened to extend beyond the inner ends of the guide strips 2| to retain the shield in place from that direction. In other respects the construction and use of this form of protector are the same as described in connection wit-h Figs. 1 and 2.

Although I have herein shown and described a preferred embodiment of my invention, manifestly it is susceptible of modification and rearrangement of parts without departing from the spirit and scope thereof. I do not, therefore, wish to be understood as limitin this invention to the precise form herein disclosed, except as I may be so limited by the appended claims.

I claim as follows:

1. A look protector for covering and enclosing a lock on a door, comprising a shield, one end of said shield having a swingable closure member thereon, means slidably securing said shield to the door, and stop means on the door for retaining said swingable closure member in closed position, said stop means also retaining said shield against removal in one direction.

2. A look protector for covering and enclosing a lock on a door and coacting with the jamb of the door, comprising a shield having a swingable closure member on one end, means slidably securing said shield to the door, said shield being in position'for abutting the door jamb without substantial movement when the door is closed, and said shield thereby being held against removal by the dooraamb, .and meansronthe door for retaining said swingable closuremember'inhlosed position.

3. A look protector for use on a door, comprising a shield adapted to fit over a lock on the door, one end of said shield having a swingable closure member thereon, means slidably securing said shield to the door, said closure member being swingable :toopen position for sliding the shield over the lock in a direction from the free edge of the door, and stop .means on the door spaced from the lock in the "direction the shield is slid over the lock, said closure member being swingable to closed position after passing the lock in the sliding operation and before reaching the stopmeans, said stop means retaining said closure member in closed position and the shield in place on the door.

4. A lock protector for-use on a door and coacting with the jamb thereof, comprising a shield adapted to fit over a lock on the door, one end of said shield having a swingable closure member thereon, means slidably securing said shield to the door, said closure member being swingable to open position for sliding the shieldover the lock in a direction from the free edge of the door, and stop means on the door spaced from the lock in the direction the shield is slid over the lock, said closure member being swingable to closed position after passing the lock in the sliding operation and before reaching the stop means, said stop means retaining said closure member in closed position and the shield in place on the door from movement in one direction, and the jamb retaining the shield in place on the door from movement in the other direction, when the door is closed.
